DECORATIVE LIGHT F iled March 16; 1936 Patented Sept. 14, 1937 DECORATIVE LIGHT Arthur Stechbart, Chicago, Ill., assignor to Matchless Electric Company, Chicago, 111., a corporation of Illinois Application March 16, 1936, Serial No. 69,089

7 Claims.

This invention relates to ornamental or decorative light devices such as is shown in the prior application of Paul C. Dittman, Serial Number 19,417, filed May 2, 1935, now Patent No. 2,063,153.

In devices of this character, the problems of mounting and securing the crystals or solid prismatic bodies of glass is one of the principal problems in the construction of such devices. The intrinsic value of the crystals is such that it is preferableto continue their use much longer than the life of the light bulb utilized to illuminate such devices.

One of the purposes, therefore, ofthe present invention is to provide in an assembly of this character a novel mounting for the light'bulb whereby new light bulbs may be applied to the crystal structure without the necessity of any particular tools or implements. In other words, it is the purpose of the present invention to so construct the light unit that the ultimate purchaser who uses the unit as an ornamental light can, with little or no difficulty, transfer the crystals to a new light source without the aidof special tools or machinery.

It is another purpose of the present invention to provide a novel base structure for mounting the crystals and positioning them with respect to the light source.

A further purpose of the invention is the provision of novel interlocking mounting units whereby a plurality of rows of crystals may be connected together and to ,a. supporting base.

It is a further purpose of the present invention to provide in a device of' this'character a radially about a common center.

A further purpose of the invention is to provide a novel center .crystal supporting and pointed crystal positioning unit for devices of this character.

Other and more specific objects and advantages of the invention will appear as the description proceeds in connection with the accompanying drawing wherein the preferred form of the invention is shown. It is to be understood, however, that the drawing and description are illustrative only and are not to be taken as limiting the invention except in so far as it is limited by the claims.

Referring-now in detail to" the drawing, the decorative light structure is made up essentially of a light bulb l0,a mountingbase II, a large back row I2 of elongated prismatic glass bodies,

a second row l3 ofsmaller glass bodies similar in shape to the row I2, and a central ornament or crystal 14, In many aspects, the invention is elongated pointed crystals that :entrap light en teringthe crystals from one endand cause'it to be reflected from at least one face of the crystal before it can bedirectedoutwardly from the crystal; The crystals, as shown, are provided with sixteen faces, and the faces run from :the end points substantially to the center along'the longitudinal axis of the crystal. The faces, however,

are cut in such a fashion that the line adjoining two faces running from one point strikes about the center of a face running from the other point of the crystal. The angles the several faces make with the longitudinal axis of the .crystal are approximately 20 degreesso that the angle between two opposite faces of the crystal is substantially 40 degrees. crystals radially about the light bulb and have the side faces thereof substantially parallel to each other. The inner ends of .the several crys-i Thus it is possible to arrange nine tals are cut off as indicated at 15 and IS in Fig. 2

for the purpose of permittinginore light to enter the crystals. 1 H

V 'The mounting of the crystals upon the 'base I i is particularly important because this base must determine the position of the crystals with re-" spect to the light source and the position of the crystals with respect to eachother. The base 'II is molded of any suitablecomposition and is provided with 'a central recess I1 and a reduced opening 'at I8 to receive'the light bulb It. The

light bulb iii, of course, has the usual filament in radially arranged depressions -2 lffs'epa'rated by V-shaped portions 22. The depressions 2-! are:

formed substantially parallelv to the lower-three faces 23,24, and 25 of'anadjacent crystal in the securing ring 26 is made of a stripof sheet metal and is bent to fit snugly against the top surface of the base ll.

which will be presently described. The ring 25, however, is the sole connection between the base H and the crystal structure. This ring is releasably secured to the base H by a plurality of tongues 27, 28, and 29 extending from the ring and bent over beneath the lower surface of the base H. The material of the tongues is preferably made soft enough that it can be readily bent so as to release the tongues from the base I l and thus permitremoval of any crystal structure from the base without any tools or equipment other than would be commonly found in the home.

The replacement of the light bulb 10, therefore, becomes a simple matter since the owner of the crystal structure need only purchase the light bulb equipped with the base II.

The several crystals making up the row 12 are secured together by means of a wire loop 38 which is threaded through openings in the inner ends of the crystals. The crystals making up the row 53 are secured together by a series of wires 3|, 32, and 33 which wiresare passed between adjacent crystals of the row l2 and are soldered or otherwise secured to the ring 26 as indicated at 34 in Figs. 2 and 4. The loose ring 30 and that ring made up of the parts 3|, 32, and33 are not,

however, sufiicient to adequately position the several crystals so I provide in conjunction therewith a binding ring 35. This ring 35 has depending fingers 36 which extend between the crystals'in the row [3 and hook under the wires 3!, 32, and 33 thus to place and position the crystals in the row l3 so that they cannot be dislodged. The ring 35 has its body portion 31 bent substantially to the shape of a frustum of r a cone. The ring 35 thus serves as a supporting and spacing device for the crystals in the row l3.

This ring also serves as a supporting and securing means for the central ornament M. This central ornament, which may be a piece of cut glass, has a conical bottom face 38 adapted to rest against the conical part 3'! of the ring 35. The central ornament also has a shoulder at 39, and the ring 35 has a plurality of fingers 4!] extending upwardly and hooked over the shoulder 39 to fix the central ornament in position. The entire ring 35 is formed of one piece, the fingers 36 being struck out from the material, and the fingers Ml being also formed in this fashion. As shown most clearly in Fig. 1, the fingers 40 are offset between the fingers 36 so that there is no wasted material to speak of.

From the above description, it is believed to be evident that I have provided a simple and efiective assembly unit for the several crystals whereby 7 they are held in position so that they cannot be Having thus described one specific form of my invention, what I claim as new and desire to secure by Letters Patent is:
